The Gebel Shalman-Wadi Biarn (GSh-WB) Niobium (Nb), Yttrium (Y), and Fluorine (F) (NYF-type) rare-metal pegmatites occur as veins, dykes, and zoned pockets hosted entirely within syenogranites. The pegmatites occur within the syenogranites in two principal forms. The first type forms NW-SE and NE-SW trending veins and dykes that cut across the syenogranite. These veins range from 0.5 to 3 m in width and extend laterally from 10 to 75 m. The second type forms zoned pockets (5 to 75 m in length and width) with gradational contacts into the host syenogranites. There are four distinct zones inside the pegmatite pockets: the border, the wall, the intermediate, and the core. Border zones (a narrow, 1–5 cm thick) comprise a narrow, fine-grained granitic rock at the interface with the host rock. Moving inward from the boundary, the wall zone (extending 15–45 cm inward from the border) exhibits a sudden escalation in crystal size and is distinguished by notable mineralization. Due to intergrowths, the intermediate zone (1–3 m width) produces K-feldspar and quartz with large crystal sizes, and it establishes gradational contacts with the wall zone. Quartz and K-feldspar were the sole constituents of the core zone (0.5–2 m diameter).
